Juno Position & Status

View of Juno’s position on Aug. 30 from NASA's Eyes on the Solar System.

As of Aug. 30, Juno was approximately 24 million miles (38 million
kilometers) from Earth. The one-way radio signal travel time between Earth and
Juno is currently about 2 minutes. Juno is currently traveling at a velocity of
about 24 miles (38 kilometers) per second relative to the sun. Velocity
relative to Earth is about 7 miles (12 kilometers) per second. Juno has now
traveled 917 million miles (1.5 billion kilometers, or 9.9 AU) since launch.

The Juno spacecraft is in excellent health and is operating nominally.
All science instruments are powered off except for the magnetometer experiment,
which continues to operate in low-power mode.

events

The Juno mission operations team successfully executed a trajectory
control maneuver (named TCM-6) using Juno’s attitude control thrusters on
August 7, further refining spacecraft’s trajectory in preparation for the Oct.
9 Earth flyby gravity assist maneuver. With the completion of this maneuver
Juno is, technically speaking, on course for Jupiter arrival in 2016. The
spacecraft must still complete the Earth flyby to receive the gravity assist it
needs in order to reach Jupiter, but the completion of TCM-6 has Juno on course
to complete the flyby as planned.

The spacecraft reaches perihelion, the closest point in its current
orbit around the sun, on Aug. 31. From that point onward, the sun’s rays will
become increasingly faint. When Juno arrives at Jupiter, the arrays will
produce about 450 Watts of electric power from a mere four percent of the light
we receive at Earth’s distance from the sun.
